What happens to equilibrium price and quantity when penalties for buying and selling marijuana increase?

When the government increases penalties for buying and selling a good, it makes it riskier and less appealing for people to participate in the market. This leads to a decrease in the quantity supplied of the good. Additionally, the higher risk associated with the good discourages people from buying it. As a result, both demand and supply decrease, leading to a lower equilibrium price and quantity.

What happens to equilibrium price and quantity when a government subsidizes day-care operators and more mothers return to the workforce?

If the government subsidizes day-care operators, it reduces the cost of providing day-care services. This encourages day-care operators to supply more services. At the same time, more mothers returning to the workforce increases the demand for day-care services. As a result, both supply and demand increase, leading to a higher equilibrium quantity but an uncertain effect on the equilibrium price.

What happens to equilibrium price and quantity when streaming costs decrease and more consumers directly stream music?

When a new processing method reduces costs for streaming, producers are incentivized to supply more music streaming content, leading to an increase in supply. Additionally, more consumers choosing to stream directly to their computers increases demand for music streaming services. Therefore, both supply and demand increase, leading to an increase in the equilibrium quantity and an uncertain effect on the equilibrium price.

What happens to equilibrium price and quantity when more people become vegetarian and regulations on organic products become stricter?

An increase in vegetarianism due to medical reports promotes the demand for organic vegetables. At the same time, tighter regulations on the definition of organic products make it more difficult and expensive for producers to supply organic vegetables, leading to a decrease in supply. This scenario results in an increase in demand and a decrease in supply. In this scenario, the equilibrium price is likely to increase, while the effect on the equilibrium quantity is uncertain.

Study Notes

Learning Objectives

  • Understand that the forces of supply and demand still apply even in non-competitive markets

  • Explain how simultaneous supply and demand changes impact equilibrium price and traded quantity

  • Explain why markets sometimes don't function optimally

  • Describe how price ceilings lead to shortages

  • Explain how price floors result in surpluses

  • Explain how production quotas affect prices and quantity

  • Explain the effects of sales taxes and subsidies on markets

Markets Matter

  • Supply and demand remain relevant even when a single corporation dominates a market

  • A "perfectly competitive" market is one without dominant firms or government interference where supply and demand determine prices

  • Competitive markets only function effectively if truly competitive

  • When many participants buy or sell in a market, the benefits of competition decrease

Example - Fusion Car Pricing

  • A firm can price a Fusion car at any desired level

  • To sell all its output it must set the price at or below $20,000

  • Offering cars for more than $25,000 would lead to unsold vehicles

LO2: Simultaneous Changes in Demand and Supply

  • When supply and demand change simultaneously, the outcome on price or quantity is uncertain unless change magnitudes are identified

Scenario 1

  • Simultaneous equal increases in supply and demand increase quantity but not price

Scenario 2

  • A greater increase in demand than supply results in both increased quantity and price

Scenario 3

  • A greater increase in supply than demand results in increased quantities but decreased prices

Conclusion- Demand and Supply

  • An increase in both demand and supply leads to an increase in the equilibrium quantity
  • However, unless change magnitudes are known, the resulting equilibrium price is uncertain

Determinants of Demand and Supply

  • Demand Determinants: Consumer preferences, consumer incomes, prices of related products, expectations regarding future prices/incomes, population characteristics (size, distribution, age).

  • Supply Determinants: Prices of productive resources, sales taxes/subsidies, technology, prices of substitutes in production, future expectations of suppliers, number of suppliers.

Test Your Understanding – Effects of Changes on Equilibrium

  • Daycare Services: Increased mothers in the workforce and government subsidies will likely lead to an increase in equilibrium quantity and uncertain effects on price.

  • Marijuana: Increased penalties for buying/selling will result in a decrease in quantity and an uncertain effect on price.

  • Music Streaming: A new, more efficient method and increase in consumers streaming music content directly onto personal computers will likely result in a decrease in price and an increase in quantity.

  • Vegetarianism: Increased vegetarianism and stricter organic food regulations will result in an uncertain effect on price and an uncertain effect on quantity

LO3: How Well Do Markets Work?

  • Markets don't always adapt quickly enough
  • Markets may produce unequal results
  • Some goods/services may not have truly competitive markets

LO4: Price Ceilings

  • Price ceilings are government-imposed maximum prices for a product
  • Price ceilings are implemented when the current market price for a product is believed to be excessively high
  • Price ceilings often cause shortages
  • Examples include wartime necessities and rental controls

Allocating Shortages in a Price Ceilling Market

  • The market (supply and demand), lottery, first-come-first-served, producers' preferences, and government rationing

LO5: Price Floors

  • Price floors are government-imposed minimum prices for a product
  • Price floors are often applied when the current market price is considered too low for producers
  • Price floors often cause surpluses

LO6: Production Quotas

  • A production quota is a government restriction on the output of a product.
  • A quota can increase the price of a product without creating a surplus

LO7: Taxes and Subsidies

  • Excise Taxes: Sales taxes on products like alcohol, gasoline, and cigarettes. Carbon taxes are also considered excise taxes. Excise taxes, whether collected from the buyer or the seller, decrease equilibrium quantity
  • Subsidies: Government payments intended to encourage production or consumption; subsidies increase quantity.
